Site and email are hosted at Siteground, we switched Nameservers to Cloudflare. Despite ALL settings being the same, emails cannot be sent.
When I examine the DNS I see the ns1 and ns2 entries still pointing to the Siteground IP addresses.
Could that be a factor?
How long has it been since the Nameservers were changed?
Sometimes nameserver propagation can take up to 24h. However, if all the records are the same there should be seamless failover. Can you verify that all MX and TXT records are the exact same?
Thanks for chipping in. Been over 12 hrs and whatsmydns.net shows the correct ones.
Had to chat with SG. Edited the server entries and all is good.
